Pythagoras in Nowadays

Updated: Jan 28, 2023

Pythagoras is an ancient Greek philosopher and mathematician who lived around 570-495 BCE. He is known for his contributions to mathematics, including the Pythagorean theorem, as well as his ideas about the nature of the universe and the soul. His philosophical and religious teachings, known as Pythagoreanism, also had a significant impact on the ancient world. Today, Pythagoras is remembered as one of the most important figures in the history of mathematics and philosophy. His work continues to be studied and referenced in both fields.




Pythagoras is considered one of the first true mathematicians and is known for his contributions to number theory and geometry. The most famous of his contributions is the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This theorem is still widely used in mathematics and is a fundamental part of geometry.




Pythagoras also made important contributions to the study of ratios and proportions, which laid the foundation for the development of trigonometry. He was also interested in the properties of numbers and is credited with discovering the existence of irrational numbers, which are numbers that cannot be expressed as a ratio of integers. In addition to his mathematical contributions, Pythagoras is also known for his philosophical and religious teachings. He founded a school in Croton, Italy, which was known as the Pythagorean Brotherhood. This school was not only a place for the study of mathematics and philosophy but also a community of like-minded individuals who shared a common way of life. The members of the community followed a strict code of conduct and had a strong sense of moral and spiritual unity. Pythagoras's ideas about the nature of the universe and the soul, as well as his ethical and religious beliefs, had a significant influence on ancient philosophy and religion. Today, Pythagoras's legacy is still remembered and studied in many fields including mathematics, philosophy, and history. His contributions to mathematics, such as the Pythagorean theorem, continue to be fundamental concepts in the field. His ideas about the nature of the universe and the soul continue to be debated and discussed in philosophy, and his religious and ethical teachings continue to be studied in the field of history.



Pythagoras is known for his emphasis on education and his belief in the importance of understanding the underlying principles of the universe. He believed that mathematics was the key to understanding the workings of the universe, and he taught his followers that through mathematical study, they could gain knowledge and wisdom. He also believed that the soul was immortal and that it could be purified through a combination of philosophical study and moral living. Pythagoras is also known for his influence on the development of music theory. He believed that the universe was composed of numbers and that the intervals between musical notes could be expressed as numerical ratios. This led to the development of the concept of musical tuning and the use of mathematical ratios to determine the intervals between notes.

Pythagoreanism, the philosophical and religious teachings associated with Pythagoras, had a significant influence on the ancient world. His ideas about the nature of the universe, the soul, and the importance of mathematics and philosophy were adopted by many of his followers and were passed on to later generations. Pythagoreanism also had an influence on the development of other philosophical and religious movements, including Platonism, which was heavily influenced by Pythagorean ideas. In conclusion, Pythagoras's contributions to mathematics, philosophy, and religion continue to be studied and debated by scholars today. His emphasis on the importance of education, understanding of the underlying principles of the universe, and the belief in a connection between the soul, music, and numbers are some of the most lasting legacies of his teachings.
